@uptimevic Hello Vic! Welcome to the Auth0 community. There are two libraries you can use: auth0js or Lock. Lock has limited customization verses the auth0js library which is fully customizable. You can use either of these options with either an embedded page or a hosted login page. Here is documentation to explain when to implement lock verses a custom ui (https://auth0.com/docs/libraries/when-to-use-lock) and the steps inorder to do so.
